TYPOGRAPHIQ MACHINE.

Specification of Letters Patent. I Patented May 17,1921.

Application filed September 12, 1919.: Serial No. 323,284.

Be it known that I, MAURITZ C. INDAHL, a citizen of the United States, residin at Philadelphia, county of Philadelphia, tate of Pennsylvania, have invented certain new and useful Improvements in Typographic Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and'to the char: acters of referenceimarked thereon.

This invention relates to type-casting and composing machines of that class wherein type metal elements are cast and ejected into a galley underthe control of a keyboard. An exemplification of such class of.

machines may beiou'nd in'the well known casting and composing machines made by the Lanston Monotype Machine Company in which the keyboard element is in the form of a separate machine for preparing a perforated paper strip or controller, which latter when applied to the casting element controls the casting and delivery of the type bodies. The present invention has among its objects to" provide a novel mechanism for selectively controlling definite functions of a casting machine of the class referred to; to provide mechanism respon sive to keyboard control, for adjusting the mold of such a machine for the production of type sizes varying in pointwise direc tion; to provide an interpreting. device whereby an impulse, due to keyboard ac tion, such as the pneumatic impulse controlled by the signals of a perforated paper controller, may be selectively utilized to govern direction ofmovement of as well as location of an'adjustable element of a casting machine of the class referred to; to provide a mechanism for moving an adjustable element of such a machine from its position at any time directly to the next position as recorded by the keyboard and without return of it'or'any of theparts for operating'it to a zero or initial position; to produce a keyboard controlled mechanism to receive location impulses and from them control direction of movement and then produce a locking of the moving parts after their movement has been completed. Other objects of this invention will be hereinafter pointed out or will other-' Wise appear inconnection with the following description of an embodiment of the invention as shown in the accompanying drawings in which Figure l is a plan view of a, well known type c'astingand composing machine embodying the present invention.

The machine the general features of which are illustrated in Fig. 1 is of awell known class for producing'individual types and requires herein no extended description; its .general organization may be; as shown in Patent 625,998 granted May 30,

1899 to LanstonMonotype Machine Co.

F or identification purposes it may be of ad? vantage to indicate by'reference characters some of the more important parts of the mechanism shown; for example, thepaper controller tower-A, the pin blocks B and] B, the matrix positioning mechanism C and C, the-mold Dthe molten metal pot E, the pump mechanism F, the cross slide G to which the matrix case (not shown) is adapted .to be hooked, the line hook H,the type channel I, the hand wheel J and its shaft K, the mold blade operating mechanism 'L ,and thenormal wedge M cooperating with the mechanism L to determine the setwise ladjustmentof the mold.

The relation and operation of these parts and of the other parts of the machine are well understood The paper controller perforations govern the selection of pins in the pin blocks B, B, and the selected pins form stops for the matrix case positioning mechanism C, C the mechanism C of which also positions the normal wedge M whereby a desired matrix in the case is properly positioned over the casting cavity of the mold D and the wedge is positioned correspondingly. The mold blade operating mechanism L, is also actuated to coiiperate with the wedge M to position the mold blade to the set size adjustment corresponding with the matrix selected, the matrix is pressed against the mold and the pump mechanism is operated to cast the type. Upon the cooling of the type, the matrix islifted from the mold and the type is ejected by a forward movement of the mold blade to close the mold cavity, the cross-block or equivalent part of the mold being meanwhile moved to a position not to interfere with the ejection of the type by the mold blade. Upon being pushed from the mold in this manner the type is carried by suitable conveying mechanism} into the type channel I and when a line has been thus ejected the line hook H and other mechanism not shown operateto move the line into the galley of the machine. Further description of the construction and operation of this machine is deemed unnecessary because of its being entirely familiar to those skilled in the art.

The selector mechanism of the present inif vention, particularly shown at the top of Fig. 1 and also in Figs. 2, 3, 4, 5 and 6, is controlled from the paper tower by suitable signal perforations in the controller strip communicating with the said mechanism through the air pipes 10 (Figs. 1 and 9) and is designed to interpret the signal impulses received by it'and thus selectively govern a definite function of the machine. As illustrated it governs the pointwise adjustment of a mold by selecting the desired number of blades of a multiple blade mold and thus the keyboard operator is able to control the point size of the'type to be produced by the machine. The mold shown (Figs. 1 and 9) is of similar structureto the multiple blade overhang type mold shown in the atent of John Sellers Bancroft and Amos Knight, Number 1328256, dated January 20, 1920. It embodies essentially the base plate 11 secured to the base of the machine, the cross block 12, the fixed blocks 13 and 1 1, the mold blades 15 and the adjustable slide 16. The mold blades are provided each with an aperture all of the apertures being in register or alinement, when allof the mold blades are in position to close the mold cavity. The slide 16 is provided with a locking extension 17 and with a pivoted lever 18 the ends of both extension and lever being adapted to move through said alined apertures of the mold blades and thus be so adjusted that the extension maintains a I definite number of .mold blades locked in 'closed position while the lever acts normally to move the remain mg blades in open position, such action of the part of the lever being due to the tension spring 19 secured at one end to the outer end of the lever and at the other end to the bracket 20 secured to the slide member 16. It will be seen that the lever 18 tends to maintain the mold open with a cavity the point size of which depends upon the number of blades controlled by the lever. In the position bf adjustment shown the lever controls three blades and the extension 17 serves to lock the remaining three blades. Movement of the slide 16 at right angles to theblades and at a time when all of the blades are closed will cause a selection of the desired number of blades for control by the lever 18 and thus determine the point size capacity of the mold. WVhen the slide is adjusted by hand a lock is desirable to hold it in adjusted position; but as shown herein the movement is caused by a nut and Worm device operated by the selector mechanism and the slide therefore requires no special lock. Further description of the mold is believed to be unnecessary in view of the disclosure in the patent above mentioned, to which reference may be made if it is desired to become acquainted with the details of the mold construction. As to its bearing upon the present invention the mold maybe of any kind capable of producing a variety of type'sizes, particularly in a pointwise direction, and being provided with adjustable means for producing the appropriate setting for the desired type size: ikewise the selector or interpreting mechanism per 86 may be utilized to'move or control the movement of other parts in response to signals in the record especially where a number of positions of adjustment are desired for the least possible number of signals and the movement is directly from one position to another.

The selector or interpreting mechanism is, in the embodiment shown, suitably located at one side of the casting machine with its selector element, which as shown is in the form of a plate, movable at right angles to the direction of movement of the mold blades 15. As shown it issupported by the bracket 21 carried by the main frame of the machine. Upon the bracket 21 is a pin block 22 above which and spaced therefromby the side supports of the casting 23 are cylinders 24 and 25 forming a part of said casting. Slidably supported upon the pin block and below the cylinders is the selector slide 26. Piston 27 in cylinder 24 is connected with piston 28 in cylinder 25 bya connecting rod 29 which has secured admitted to cylinder 24 moves the two pistons and their connection with the selector slide so that the latter is moved to the right in Figs. 2, 3 and 4. On the other hand when pipe 31 is exhausted and air under pressure is admitted through pipe 32 an opposite travel of the selector slide takes place. The pin block 22 is provided with cylindrical cavities for the air pins or plungers in plural groups in the form of a row of air pins 33 and alongside of and parallel to it another row 33". A pin of one row forms with the opposite pin of the other row a pair of pins both of which receive air simultaneously through its air pin inlet pipe 10. Each inlet pipe 10 is branched below the bracket 21 and each branch leads below one of the air pins of a pair. There are provided as many pairs of air pins as there are mold blades or other instrumentalities, sizes or positions to be thereby selectively. controlled. The air pins are individually pressed downward against the bottom plate 35 by a spring 36. The, top of each spring presses against a wall formed by reducing the size of the air pin cavities in the pin block 22,.

which when the pin is actuated rises through the pin block into one of two longitudinal staggered slots 37 and 37" in the selector slide or plate, the slot 37 being located to move over the row of plus 33 and the slot 37 b parallel with the first mentioned slot and located to move directly above the row of pins 33 These slots extend to thevright and left of a central orneutral point on the selector slide except that they overlap sufliciently so that each pin of a pair actuated at such point will rise into and through its corresponding slot;- When air is admitted to any other-pair of pins than those so located, one only of such pair of pins may protrude through its slot; the otherof such pair is prevented from rising by contact with the bottom of the selectorplate.

It will be observed that sincein every position except the neutral position, only one 7; a pin ofa pair which has received a pneumatic impulse. resulting from keyboard action may project through the plate, the latters position determines which pin of a pair may rise and thus the plate has a selective function as willlatermore clearly appear. From a single pipe 10 therefore air-under pressure will raise a pin 33 or 33 1 of a pair according to whether or not the slot 37 is located above the first pin or the slot37 is above the second pin; in other words, the position of the slots (which means of course the position of the plate) relatively to the pairs of air pins determines which of the pins of-a pair is raised; The raising ofany pin 33 of one-row through the slot 37 of the selector plate 26 causes its upper end to engage with a bell crank lever 38 pivoted to the casting 23 at 39*. The bell crank is thus tilted by the movement of the pin and operates a control or governing device in the formof a throttle 'valve e0 in a casing 41 forming part of the casting containing the cylinder25 The valve casmg 4L1 has an air pressure inlet pipe 42 through which air is admitted to the valve chamber43 When the valve 40 is pressed by the bell crank 38 air is admitted from the chamber 43* to the pipe32, previously mentioned. Upon the release of the air pin 33" the valve 40* is returned to its normal position by the pressure in the chamber 43 and in so returning tilts the bell crank back to its original -position. In such'position the pipe 32 is exhausted-to theatmosphere through the exhaust port 4 F. The construction of this valve,'which is very clearly shown particularly in Fig. 5 of the drawing, is well known and ther description here.

Likewise, when a pin 33 is raised through its slot 37? it encounters a bell crank lever 38 similar to the bell crank lever 38 but pivoted at 39 onthe opposite side of the selector plate'support 30. When tiltedby the air pin the upper arm Ofthebell crank 38 strikes against valve 40 in a casing 4C1? forming a part of the casting. of cylinder needs no fur- 24 and air is admitted from. inlet pipe 42* shaft K as will be described hereinafter.

The; pipes 10 leading to the air pinsare connected, as has been before stated, with the paper tower so that they operate 1 when a. perforation or signal in'the paper is advancedto theprop'er position in the tower, The adjusting movement of the selector plate 26 however is desired 'at'a time when r the mold blades 15 are in closedposition;

andtheir apertures are therefore'ini alinement. The signal impulse precedes-therequired adjustment time and a pin raised through its slot by such impulse may drop,

due to, the cutting ofi of air pressure, before the plate and the mold adjustment slidehas been permitted to move. w Becaus'e of this vided with a notch 33 (see Fig. 8) and such notch is designed to be engaged by a catch ordetent, there being a row of such catches 45 corresponding with the pins 33 and another row 45 corresponding with the pins 33*. The detents 45 are pivoted centrally to the pin block at 46 and are each provided with a finger 47 extending below the slide 26 for engagement with the notch 33 in the corresponding air pin. A- spring 48 connects the rear end of each detent 45 with a stud 49". in the pin block 22, so that the finger 47 is caused to be pressed normally against the side of the air pin 33*. When the pin is raised by air pressure in the pipe 10 to its maximum upper position the finger 47 engages in the notch 33 and holds the pin in its upper position until released. The detents 45 pivoted at 46 are provided each with a finger 47 and a spring48 connected with a stud 49 the arrangement of detents 45 being exactly like that of detents 45" except that the former are oppositely placedand are adapted to engage with notches in the pins 33 1 Slidable in longitudinal channels in the pin block are catch release slides 50 for the detents 45* and 50 for. the detents 45". These slides are provided with upraised projections 51 and 51 respectively, such projections being adapted to engage with the rear portions of the detents so that upon movement of the release slides against the tension of the springs 48*, 48 'tl1e detent fingers 47 47 b are pulled out of the notches 33 in the air pins 33? and 33 and the latter are forced to their normal positions by the action of coiled springs 36. The detent release slide 50 is pivotally connected at its end with a lever arm 52 and the slide 50 is similarly connected with an arm 52". The

arms 52 and 52 extend downwardly from a hub member 53 pivoted to the casting 23. This member is also. provided with a downwardly extending central arm 54 longer than the arms 52* and 52 and the central arm is attached'by the c'onnecting'rod 55 to V the piston 56, the cylinder of which is bored .=in the end .ofthe pin block 22. Air is admitted to said cylinder through the air inlet pipe '57. This pipe leads from a detent release timing device associated with shaftK which will presently be described. I

When a pin 33 is raised through a selector plate slot a finger of the detent associated with the pin will engage with the pin notch 33* and hold the pin in place even though air may be thereafter exhausted from the pipe 10 leading to said pin. At a designated time for restoring the pin to its normal position, air is admitted through the pipe 57 which causes the piston 56 to move the arm 54 and the catch release slide arms 52 and 52 and consequently the catch rej-. lease slides 50 and 50 The projections 51 are all moved back to the left, Fig. 4, and one of such projections engages with the rear end of any detent which has its finger 47 in the slot of the raised pin. The projection 51 thus moves the rear end of the detent against the tension of its spring and removes the finger from the slot so that the air pin may be. restored to its normal position. A spring 58 secured to the cylinder 24 and the arm 54 returns the slides 50 to normal position when air is exhausted from pipe 57.

g The selector plate 26 is provided with a rack 59 in mesh with a pinion 60 on the end of a shaft 61, the latter. shaft, as will be seen in Fig. 1, extending parallel with the mold blades and the mold blade operating devices 'and being supported in bearings 62 sup ported on-a fixed bracket near the rack 59 and bearings 63, 64 on the frame of the cast.- ing machine in proximity to the mold. Between the bearings 63 and 64 there is provided a worm 65 engaging with the nut 66, the worm and nut being shown more particularly in Fig. 7. A pin 67 shown in said figure extends through an aperture in the nut and is seated in the two bearings 63,.64 thus preventing the nut from turning. Rotation of the shaft 61 will therefore produce a movement of the nut longitudinally of said shaft. A bell crank lever 68 centrally pivoted to the frame ofthe machine at 69 has one end connected with the nut 66 by a pin and yoke connection, the other end of the lever being connected with the slide 16 ofthe mold by a similar connection. It will be apparent that a movement of the selector plate causes a movement of the shaft and of the bellcrank lever 68 to slide the mold slide 16 in one direction or the other depending upon the direction of movement of the selector plate. I a

The selector plate timing device previously referred to may be simply an air valve operated to connect the pipe 42 with air under pressure for controlling the operation of the selector plate similarly the detent release timing device may comprise another valve for controlling the admission of air under pressure to the catch release pipe 57. The devices may. conveniently be attached in proximity to hand wheel shaft K which latter rotates at a definite relation to the various movements of the machine. On this shaft K, as shown, are the cams 7.0 and 71 operating respectively the bell crank levers 72 and 73 (see Figs. land 9); the former lever when engaged by the raised portion of the cam operates a suitable valve such as the well known button valve 7 1 (Fig. 9) to cause air pressureto pass from the constant air pipe into pipe 42 leading to the selector plate cylinder throttle valves 4:0 40?; the latter lever 73 is operated similarly by the cam 71 to admit air through valve 7 6 from pipe 75 to pipe 57 and thus cause a release of the air pin detents. Both levers when they have ridden off the high places of their cams return their valves to exhaust the "pipes 42 and 57 respectively, the return of the levers and valves being assisted by springs as 72.

The air pins 33 are blown up directly from the paper tower and when so raised operate to open one or both of the throttle valves 4:0 and 40. Air under pressure can not traverse these valves to the power cylinders 24, 25 until the pipe 42 is connected with air under pressure 1n pipe 75. Moreover in the machine illustrated it is not desired to admit power to these cylinders to cause movement of selector plate 26 and, re sulting therefrom, of mold slide 16 except when the apertures in the various mold blades are in alinement; in other words, when the mold blades are in closed position. Accordingly the cam 7 O is arranged on shaft K in such manner as to effect communication between pipes 75 and 42 when the mold blades are in closed position. fact that in the particular type of composing and casting machine illustrated this condition of mold closure occurs very much later in point of time than the admission of air to the air pins by the paper controller it is necessary in this case to provide air pin catches such as have been described. These catches take hold, as has been stated, immediately upon the sufiicient raising of the air pins. Their release is governed by the cam 71 which is arran ed to act upon bell crank 73 to open valve 6 so as to establish communication between'constant air pipe 75 and pipe 57 at a time after the selector plate has been moved to selected position and'before' the advent of another signal impulse to raise an air pin for the next selection.

The arrangement provides a retarded action which permits the record signals to set parts to effect selection of positions of other parts but the actual selection and final movements are effected at a different time in the rotation cycle of the machine with the result that the timing may be made correct without imposing destructive strams or speed to the moving parts.

"In the operation of the casting machine the paper controller is fed forward in the paper tower A step bystep; its perforations may control matrix selection or other functions of the machine; and for the 1llus- Because of the tion the controller is assumed to have a perforation signal to communicate properly with a pipe 10 leading to a pair of pins 33*, 33 below the selector plate 26. Air under pressure immediately tends to force these pins upwardly and results in the raising of at least one of them, which on rising extends into or through one of the slots 37 37 in the selector plate and tilts one of the levers 38 38 to open one of the valves 40*, 40 Also, upon reaching its raised position a catch 415 or 45 will hold the pin in such position in the way alreadyxd'escribed. The position of the plate at. any time determines whether both pins 33 of a pair shall rise to lock the plate against movement, or only one of such pair and in the latter case which one of the pair to control movement of the plate to a new position. The selected pin determines which valve of the pair 40 40 is opened andconsequently in what direction the-plates shall be moved. The movement of the plate is therefore direct from one position to the. next without any return to a zero or initial position by it or by any of the parts by which it is operated. The cam 71 on shaft K, turning in the direction indicated by. the arrow in Fig. 9, thereafter, that is, at a time when the mold is closed, operates "to open the valve 74 whereupon air under pressure passes from pipe 75 to pipe 42'and thence through the open valve of the pair of valves 40*, 40 to the corresponding one of the pair of power cylinders 24 or 25. Assuming then an air pin 33? is raised through the-slot 37 a and causes the opening of valve 40* and is caught and held by a catch 45 upon the opening of the timing valve 74 air from pipe 4-2 will trave erse valve chamber 48 and pass by the open valve 40'' into pipe 82 leading to. cylinder 25. In the meantime cylinder 24 is open to exhaust through pipe 31 and exhaust port 44" of closed valve 40'. The pistons in cylinders 2 land 25 are therefore moved by the pressure in the latter cylinder and this movement causes a movement of the selector slide against the raised air pin. Such movement 26 to the right as seen in Fig. 9 until its is arrested bytlie abutment 37 formed as shown by the end of; its slot 37 striking causes a rotation of the shaft 61 and 0011- sequently movement of mold slide 16 to select the number of blades corresponding with the particular 1.11 pin which has been raised by signal. It isclear, of course, that the blowing'up of a pin 33 would similarly result in an opposite movement of the se lector slide 26 until its abutment 37 engages the operated pin, and of the mold slide '16. When the selector slide is in middle position, as shown, the mold slide, it

will be noted, is also in -middle position,

having selected three'of the siX blades. It

.may also be pointed out that in whatever position the selector slide is left a. controller signal calling for no change of selec '40 are opened and air will subsequently be admitted to both cylinders 24, 25. The result will be an equalization of pressure and consequently no movement of the selector plate. It'is to be noted also that when both pins of a pair are raised the plate is locked against movement, the inner end of each slot 37 37* being stopped against an air pin. This locking feature is operative in any case in which air pressure against the air pins is sufiiciently prolonged or in which the paper controller signal and the adjustment are adapted to take place substantially at the same time because if at first one pin of a pair only rises, it accomplishes a movement of the selector plate to position the inner wall of its slot agalnst the said pm and the second pm wlnch has meanwhile pressed against the bottom of the plate will also rise into its slot when the above positioning has been accomplished hen both pins are raised the plate will be locked against movement in either direction.

Obviously the inner end walls 37, 37 of the slots in the plate simply form shoulders or abutments for contact with the pins and hence the formation of slots is not essential but is a convenient and cheap construction@ I claim:
